PHASE-ONLY SHAPING OF LIGHT PULSES FOR APPLICATIONS IN QUANTUM TECHNOLOGIES<\/h1>\n

A research project within the First Team Programme of the Foundation for Polish Science<\/h3>\n

THE PROJECT<\/h4>\n

Optical pulses form the backbone of photonic technologies. Their key characteristics are their temporal profile and their frequency spectrum. Experimentally, only one of these two parameters can be easily accessed, due to the incompatibility of time and frequency resolutions of detection and manipulation devices. The power of quantum mechanics manifests itself chiefly through the superposition principle: if two states of a system are valid quantum states, then their superposition is also a valid quantum state. The emerging quantum technologies are based on the ability to create, manipulate and detect quantum superpositions, which relies on the ability to access conjugate variables, such as the time and frequency for single-photon pulses. Here we will use novel tools to experimentally access temporal and spectral characteristics of quantum light pulses. We will manipulate and detect their quantum superpositions, and demonstrate their applications in quantum networks and metrology.<\/p>\n

PROJECT GOALS<\/h6>\n

Experimentally modify the spectral and temporal properties of single-photon pulses. We will convert photons from solid-state emitters to photons fully compatible with high-bandwidth telecommunication channels. We will investigate applications of shaped quantum light pulses in quantum metrology.<\/p>\n

PROJECT OUTCOMES<\/h6>\n

Construction of electro-optic and nonlinear optical devices enabling modification of spectral-temporal properties of single-photon pulses. Training of scientists towards their Master’s and PhD theses and training of post-doctoral researchers.<\/p>\n

PRACTICALITIES<\/h6>\n

The project was carried out at the Quantum Photonics Lab at the Faculty of Physics of the University of Warsaw from 2019 to 2024 under the lead of Dr Micha\u0142 Karpi\u0144ski, in collaboration with prof. Nicolas Treps from Sorbonne University in Paris<\/a>, prof. Peter G. R. Smith at the Optoelectronics Research Centre in Southampton, UK<\/a>, prof. Christian Becher at the Saaraland University in Germany<\/a>, Dr Robert Keil form the University of Innsbruck in Austria, Prof. Paul Kwiat from the University of Illinois at Urbana-Champaign (USA) and the French Quandela company! The project was financed through the FIRST TEAM programme of the Foundation for Polish Science. The total value of the project was 2 915 024 PLN (approx. 600 kEUR). It was fully funded by the European Union’s European Regional Development Fund.<\/p>\n
